Abstract:
Novel hierarchical niobium-containing zeolites were synthesized for the first time and applied for isomerization of dihydroxyactetone to alkyl lactate and lactic acid (95–97% yield). These materials possess secondary mesoporosity, thus facilitating access to active sites of the material by larger reagent molecules, preserving acidity and crystallinity of the zeolites.
